Yes, volgain works fine, unfortunately it is only useful for emailed
wav files. That's why I was trying to get the g(#) option to work. I
suppose I could try to hack together a shell script using sox and call
it from externnotify. Does anyone know if there are drawbacks to this
approach? Any other thoughts or options?

Thanks,
